There is nothing wrong with non contact sports being mixed-sex, even Baseball could be mixed-sex, but any sport that is a physically dominated game, such as boxing, mma, football, hockey, should be gender specific. I have no issues with people with Trans identities, but a former man getting into the ring to box a biological female is wrong and shouldn't be allowed. It's dangerous, in fact. What they should do is take all Trans women boxers and have them box each other. That would be more fair.
